what does this mean?
No or very poor cable signal.
Normally yes, this error means that the signal for that equipment is weak or disconnected.
The first thing to check would be the coax cable coming from the wall and plugging into your set top box. Disconnecting and reconnecting this cable is often all that is needed.
If not, there could be a problem with that box's activation and may need to be reactivated by tech support.
There is also the chance there is an issue in the area.
